Does anyone know the Rockwell hardness of the CPM-M4 steel of the C134CF Gayle Bradley? What about the S30V of the C129CF Cat?

Thanks!

I'll take a stab at it... :p ... C134CF between 62-63 and C129CF between 58-60...

There was a thread at BF on the GB. IIRC the target was 61-62 but one tested at 64. If I find the thread I'll post a link here for you.

Here's what Sal posted on that:

I've got the same question about the Bradley and hope there's confirmation of the "closer to 65" reading some time this week. I'd be very happy if Spyderco's tests also show somthing close to 65.

My Bradley should be tested sometime next week and I'll report back.
